What would be the last mystery/thriller to be on Broadway? Getting Away with Murder was in 1996. There were revivals of Wait Until Dark and Night Must Fall in 1998 and 1999. Have there been any since?
(I would not classify A Soldier's Play as a mystery. The investigation is an avenue to explore the theme of racism. The identity of the killer is not the point of the play. And I realize that mysteries and thrillers are not the same thing. I guess it's really two separate questions.)
